WASHINGTON (CNN) - She's America's top teacher, but last night Secretary of Education Margaret Spellings was put to the test herself - appearing on 'Celebrity Jeopardy' - the first cabinet secretary ever to do so.

Spellings placed second and won $25,000 for 'ProLiteracy Worldwide,' a non-profit organization that fights adult illiteracy.

Despite a strong second round, Spellings was unable to overcome the solid lead established by fellow contestant Michael McKean - the actor best known for his role as 'Lenny' on the television show "Laverne and Shirley."

Proving she is well versed on America's literary classics, Spellings answered the 'Final Jeopardy' question correctly - "What is 'To Kill a Mockingbird'" - and easily beat out Hill Harper, from the television show "CSI: NY."

While pleased with her performance, Department of Education Spokesman Trey Ditto says Spellings would like to return to America's top quiz show for another try.
